Hybird tea rose plant named Dor Jure

ABSTRACT

A new variety of hybrid tea rose having red and silver flowers.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the hybrid tea rose class, which was originated by my crossing as seed parent the variety known as `Pharaon` and as pollen parent the variety known as `Osiria`. The varietal denomination of this new rose is `Dor Jure`.

Among the novel characteristics possessed by this new variety which distinguishes it from its parents and all other varieties of which I am aware are its attractive bicolor flowers having red coloring on the petals top surface and silver coloring on the petals's reverse (undersurface). The flowers are large and are borne singly in a manner typical of hybrid tea varieties and on a plant suitable for growing outdoors in gardens.

Asexual reproduction by propagation by budding of the new variety as performed in Clackamas County, Oreg. shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations. The new variety can be asexually propagated by budding, grafting, micropropagation and from cuttings.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows typical specimens of the flowers and vegetative growth of the new variety depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character. Colors may vary depending upon growing conditions under different climate, soil, and cultivation conditions.

DETAILED DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of my new variety, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.). The terminology used in the color descriptions herein refers to plate numbers in the aforementioned color chart.

Parentage: Seedling.

Seed parent.--`Pharaon`.
